Acer Aspire M5 481T consuming power while turned off! Battery drains with system halted!

[Waldemar Silva Júnior]

Guys, I'm facing this problem just since I installed Ubuntu 15.04. The laptop came with Windows 8 installed and this problem didn't exists there. Everything seems to run just fine, but when I turn it off with 50% of battery for instance there is no energy after some hours and I can feel that the laptop is a little hot, but there is no noise like anything was on.. What could be happening? I've searched for some solution, already tried to include some options in grub config like noapic, nolapic, irqpoll, acpi=off and others without solution. Also tried to check WOL but it's ok too. What could be happening? How to solve this problem?

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.2 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Joseph, I've just tried the latest upstream kernel and the problem persists, same thing.

Running Mint 17.3 KDE on a Toshiba P55t-B5154 dual-boot with Windows 10. If I shut down the laptop from Windows, the battery remains 100% when I power up in the morning. If I shut down from Mint, the battery is drained sometimes to 70%depending on time between power-down and power up.

[Bananabob (bananabob)]

I am running Linux Mint 17.3 Cinnamon with kernel 4.2.0-18.

I power off using the Menu>Quit>Shut Down sequence. My battery indicator shows 100% at power off
When I reboot in the morning the battery indicator shows 60%.

In trying to ascertain if this was a hardware or software problem I have tried the following:

I used the Menu>Quit>Restart sequence and let the laptop start to boot into Windows. I then hit the power off button. The next morning on booting into Linux Mint the battery indicator showed 100%.

I also tried just closing all applications in Cinnamon and then hitting the power off button. On power on and reboot the next morning the battery showed 100%.

I then tried closing all applications in Cinnamon and opening a terminal and issuing "sudo shutdown -h now" - Next morning on reboot the battery showed 60%ish.

I also tried Menu>Quit>Shut Down and removing the battery - Next morning booted into Mint after reinserting the battery and power was indicated at 100%.

This would indicate to me that the problem is related to Linux in some way.

Last night I switched from the NVIDEA drive to the Intel driver for graphics and then powered off.

This morning my power drop was only 7% - It dropped from 100% to 93%.

So I am assuming it is a problem with the NVIDEA drivers.

Anyone care to comment

I used this site to disable WOL before shutdown: http://www.hecticgeek.com/2012/09/disabling-wake-on-lan-in-ubuntu-might-save-a-tiny-bit-of-power-on-your-laptop/

I lose about 1% battery an hour when shutting the machine down from Linux. WOL is off in UEFI, and Windows shutdown works the way it should.

My machine uses a Radeon R9 M265X graphics chip, so I'm not sure it's only a video driver issue.

I wonder... wake on USB? Wake on clock?

[Bananabob (bananabob)]

Re my comment above - I should have said Nouveau Drivers - It is an NVIDEA Card.
I am referring to using the PRIME option to switch from Intel to NVIDEA card

@dngrsone that is the site I used to confirm that my WOL is off. Do you have an integrated video card as well as the Radeon and can you switch to integrated?

This did not work.
